how do i know when mouth breeders have eggs? and how will i know when she is ready to spit? and am i best of putting the female by its self to spit the eggs?
Most mbuna hold for 21-28 days, you'll know she's getting close when she has a hard time closing her mouth anymore, sometimes if you look very closely you can even see the eggs or fry.
If you want to keep all of the fry, then yes, it is best to move her to another tank, then either strip her, or let her spit.
Here's some more information on breeding and raising fry.
